Download calibre, an e-Book Management Application

I've always looked for a way to manage all the scattered e-books that i had on my computer and i'm confident to say or type as the case may be that i just discovered a perfect application that manages all my e-books and even does a little more than just management.

The name of the application is calibre (yes, small c cause the developer wants it spelled
like that).
It can mange e-books of different kinds such as ePUB, pdf and mobi format, it can even convert between those formats and it runs on Windows, Mac and Linux.

I cannot begin to list a full list of features but i think that it will be worth it if you check out their website and possibly download the app that fits the platform that you are using.
